Eaton Bussmann - Products for sustainable energy
720110 10x38 mm PV fuses
The PV-4A10-T offers a 1000 Vdc rating with a 4 A nominal current and a 50 kAIC interrupt capability, delivering robust protection for PV strings and reducing arc energy during fault events, which lowers equipment damage and maintenance costs in industrial solar installations. This is complemented by a 1-3 ms time constant under IEC 60269-6 type A (Class gPV), ensuring fast fault interruption and enhanced system safety across high-voltage PV networks and string combiner applications. The non-indicating design minimizes panel clutter and maintenance overhead while providing reliable protection in harsh outdoor environments. Bolt fixing, together with a compact 10 x 38 mm fuse size (62 mm length x 52 mm width x 25 mm height) and a weight of 11.3 g, supports rapid installation and easy integration into CHPV modular fuse holders. Compatibility with CHPV holders simplifies procurement and stocking for solar projects, while RoHS compliance and CE marking streamline cross-border procurement and regulatory adherence. The device’s UL Listed, CSA Certified, and IEC Rated certifications reinforce compliance for multinational deployments, reducing sourcing risk and accelerating project timelines.

FAQs
The PV-4A10-T is designed for bolt fixing and is compatible with CHPV modular fuse holders. Begin by locating the CHPV holder within the inverter or combiner box, align the fuse with the holder’s contacts, tighten the bolts to the manufacturer’s torque specification, and verify a secure electrical connection. Follow lockout-tagout procedures and refer to the Eaton datasheet for installation torque values and clearance requirements.
PV-4A10-T carries UL Listed, CSA Certified, and IEC Rated marks, along with CE and RoHS compliance. This combination supports regulatory alignment across North America and Europe, simplifies supplier qualification, and reduces project risk when sourcing PV protection devices for commercial and utility-scale solar arrays.
The 1000 Vdc rating enables protection directly at high-voltage PV strings, which reduces the need for multiple lower-rated fuses in series and improves protection accuracy. Combined with a 4 A rating and 50 kAIC interrupt capability, it supports safe, reliable operation of modern PV installations and minimizes arc energy during faults.
Yes. The non-indicating design reduces maintenance checks while the bolt-fixed 10 x 38 mm format simplifies replacement in crowded enclosures. Its robust RoHS/CE compliance and multiple certifications also lower procurement risk and downtime caused by regulatory issues, supporting long intervals between service events in outdoor solar environments.
PV-4A10-T uses a 10 x 38 mm fuse size with a total package length of 62 mm, width of 52 mm, height of 25 mm, and a weight of 11.3 g. It is designed for bolt-fix installation and is compatible with CHPV Modular fuse holders, enabling straightforward integration into standard PV protection schemes.
